ELECTRONIC APPARATUS FOR FACILITATING VISION-IMPAIRED PERSONS' INTERACTIONS WITH THE ENVIRONMENT

摘要

The invention relates to an electronic apparatus for facilitating the interactions of persons with sight deficiencies with the environment, which is attachable to a walking stick for vision-impaired persons. According to the invention, the electronic apparatus comprises a mechanical support (1) adapted to a walking stick (2) for vision-impaired persons, which contains a programmable control unit (3) with some sensitive elements attached at its inputs: an ultrasonic sensor for detecting the obstacles within the plane of travel (4) and for detecting the obstacles at the level of the user's head (5), a photoresistor (6) and a triaxial gyroscope (7) while, at the outputs of the programmable control unit (3), the active elements are attached: an electromagnetic vibrator (8), a piezoelectric loudspeaker (9), a linear LED array (10), the electronic components being supplied from a battery (11) and an on-off switch (12).
